Golden magic approximates simple intervals in the 2,3,7,11 subgroup very closely and 5 somewhat less closely (in fact 5 has the highest error of any identity in the 11 limit). Here's the 41 tone MOS with a JI detempering in the 2,3,7,11 subgroup:

The highest error of any interval in the 1,3,7,9,11 tonality diamond is 9/8, which is 4.281 cents sharp, and the lowest error is 0.012 cents, for 11/6. Golden magic tempers out the Saluzo comma, a.k.a. [[Pentacircle comma]], as well as the Saquinzo comma. Furthermore, five generators of golden magic equal the perfect fifth in [[Peppermint-24]], and golden magic can be construed as a close rank 2 approximation of Peppermint, with the quasi-diesis being 57.543 cents.

The extension of golden magic to the full 11 limit also tempers out the [[Magic comma|Laquinyo comma]], the [[Septimal kleisma|Ruyoyo comma]], the [[Sensamagic comma|Zozoyo comma]], and the [[875/864|Zotriyo comma]].
 
Golden magic can be extended to the 13 limit by tempering out the [[364/363|Tholuluzo comma]] and the [[praveensma|Thoquadzo comma]]. The 63 tone golden magic MOS has a copy of the 9 tone [[praveensma|praveensmic]] MOS as well as the 18 tone 3-MOS.

A tuning that consists of alternating downmajor thirds at 380.819c and upmajor thirds at 438.362c is recommended as it makes the stretches needed to play 11 limit chords on a Kite guitar more manageable.
